Bangalore Nagarathnamma, Indian Carnatic singer and activist (died 1952)

Bangalore Nagarathnamma was an Indian Carnatic singer, cultural activist, scholar, and devadasi. A descendant of devadasis, she was also a patron of the arts and a historian. Nagarathnamma built a temple over the samadhi of the Carnatic singer Tyagaraja at Thiruvaiyaru and helped establish the Tyagaraja Aradhana festival in his memory. Within a male-dominated festival, she was the feminist strong enough to ensure that women artists were given equality to participate in it. She "was among the last practitioners of the devadasi tradition in India," and the first president of the Association of the Devadasis of Madras Presidency. She also edited and published books on poetry and anthologies.

Carnatic music is a system of music commonly associated with South India, including the modern Indian states of Andhra Pradesh, Karnataka, Kerala, Tamil Nadu, Telangana and southern Odisha. Most Carnatic compositions are in Telugu and Sanskrit.
